Essentially the Gan 11 M PRO is a very nice cube, I have done no set-up on it and yet have already broken my PB AO50 and AO100, the corner-core magnet system does seem to work very well and while I suspect that is the only new thing other than the factory lube combinations, it definitely works very well. It has the full range of corner cutting expected. I will soon create a full review of this cube.
